DOVER — Meteorologist Andy Pohl with the National Weather Service said a more comprehensive update on the storm will be available at 4 p.m. today. He said “specifics” are still uncertain but the Seacoast should see some rainfall from Monday afternoon in to Tuesday, with strong winds on Sunday.

“We're trying to impress upon people where ever the storm makes landfall is not as important” Pohl said, noting forecasts say Sandy will strike the U.S. first in New Jersey. “It's a very large storm, and extends hundreds of miles. Much of southern New England will be affected.”

Somersworth has announced a storm shelter will be available at the high school during the storm, as well.

Several communities have moved their planned trick-or-treating times to Sunday evening. Hampton has rescheduled for Sunday, Oct. 28, from 5:30 to 8 p.m. along with Newmarket, from 5 to 8 p.m., Kittery, Maine, from 5 to 8p.m., Rollinsford from 4 to 7 p.m. and Lee, from 5 to 7 p.m.
